Factory reset? No. Wouldn't that effectively wipe out the firmware update?

No.

Or does the firmware update live through the factory reset (I wouldn't expect it to live through that).

Yes.

A reset just erases any settings that you have applied to the current firmware. The firmware itself lives on.

New firmware sometimes introduces changes that are not compatible with the old configuration.

So while it isn't guaranteed to fix problems a factory reset is the first thing to try if you have issues with new firmware.

You can reduce the hassle of reconfiguring all those settings by creating a backup of your settings before you reset. Then if something is still broken after the reset, and the new firmware has not fixed it, you can restore the device to its pre-reset state.

You could even try restoring the settings even if the new firmware has fixed the problems, but be prepared for the restore to also bring back your problems.

I have been getting DNS errors since a firmware update recently. I have noticed that it happens with wired devices but not (or less often) with WiFi devices.

I have been able to work-around the problem in Windows 10 by changing the Windows DNS server so it bypasses the NetGear router. By default Windows finds the first router upstream and uses it's DNS settings to run a DNS lookup. You can manually change a setting so that you can tell Windows what DNS server to use. You can direct it to a public DNS server like Google (8.8.8.8) or Cloudflare (1.1.1.1)

Windows 10 Settings

Network & Internet

Status

Click "Properties" under the Network connection you are using.

Scroll down to "IP Settings"

Click "Edit" under "IP Settings"

Change Settings from "Automatic (DHCP)" to "Manual"

Turn IPv4 "On"

Set "Preferred DNS" to 1.1.1.1

Press "Save"

For me, this fixed the problem immediately.

You might have to run these commands from the command prompt to clear your local DNS or just reboot your PC.

ipconfig /flushdns

ipconfig /renew

I still hope there is a firmware update so I can set this setting back to Automatic.

Thanks, but for me, unfortunately, bypassing the router is not a good option. Too many machines to update manually. More than one is too many for me, sorry NetGear.

re wired vs wifi

I've also noticed mobile devices weren't getting errors neither. However, I'm wondering if they web calls had multiple attempts in such a way that the problem is not evident to the user. Just a guess. 

Going back to the January version worked for me.

Well I am a happy user for both my R6400v1 and R6400v2

I did the same on my PC and Boom! instant fix. The other PC's at home (wifi and wired) still have problems. Mobile devices and my TiVo seem fine as do my Alexa devices.

I still haven't decided where the crossover point is that the ongoing hassle of the partly functional Netgear router outweighs teh cost of buying something else that (hopefully) works. I keep checking daily for a firmware update. And the pre-thanksgiving sales for prices.
